• [Multi-Function Display]: Single-button operation seamlessly cycles between voltage reading and battery percentage display. The configurable backlight and sleep mode settings provide customized visibility while maintaining ultra-low power consumption under 5mA.
• [Accurate Battery Protection]: Integrated warning system triggers prominent display flashing when capacity falls below 20%. This proactive alert prevents deep discharge damage and extends battery lifespan by maintaining optimal charge cycles.
• [Universal Compatibility]: Supports 12V-84V systems across lead-acid, lithium-ion, LiFePO4, and battery technologies. Automatic voltage detection ensures precise readings without manual configuration for most applications.
• [Simplified Installation]: Pre-wired design with 30cm cables enables direct connection to battery terminals. Reverse polarity protection safeguards against installation errors, requiring no external power source or complex wiring.
• [Application Guidance]: Ensure proper battery type selection in settings for accurate percentage readings. Regular calibration according to manufacturer specifications maintains long-term measurement precision across seasonal temperature variations.
